Wow, Thanks, Eric!
For book references, it works straightaway! For more general use, this part
would need tweaking:
removeprefix[@book
The "book" part is actually important in the bibtex system, since it
belongs in the type-field.
Of course, filling in the type field manually isn't any trouble, but the
current bit of code seems to fail if the input has something else (like
@article) in that initial position.
Looking forward to spending more time following up on all the posts here.
